TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Dec. 12, 1905.

To all whom, it may concern:

Be it known that I, MORRIS W. PooL, a citizen of the United States, anda resident of the borough of Brooklyn, city of New York, in

the county of Kings and State of New York, have invented certain new anduseful Improvements in Type-Writing Machines, of which the following isa specification.

This invention relates to type-writing machines, and has for its mainobjects toprovide a support for the paper on which erasures mayconveniently be made and to provide a mountingfor the paper guiding andholding means.

My invention consists in certain features of construction andcombinations of devices, all as will be hereinafter more fullydescribed, and particularly pointed out in the concluding claims.

In the accompanying drawings, Figure 1 is a top plan view of the platenand the platenframe of a type-writing machine, showing my inventionembodied therein, certain parts being omitted for the sake of clearness.Fig. 2 is a sectional side elevation taken on the line w of Fig. 1. Fig.3 is an enlarged perspective view of the supporting-arm of thepaper-finger. Fig. 4 is a view similar to Fig. -1, showing amodification of the invention. Fig. 5 is a view taken on the line y y ofFig. 4, various parts being omitted. Fig. 6 is an enlarged perspectiveview of the paper-finger shown in Figs. 4 and 5.

Considering first Figs. 1 to 3, inclusive, 1 is the top plate of themachine, and 2 one of the posts for the guiding and supporting rails 3for the platen-carriage 4. The grooved back bar 5 of the platen-carriagecooperates with the rails 3 through roller-bearings, and the side bars 6and 7 serve to support the platen 8. The paper, which is represented bythe dotted line 9 in Fig. 2, is fed around the platen in a manner wellunderstood, passing into the machine over the paper-table 10 andpaper-apron 11 in rear of the platen. The side bars 6 and 7 are formedwith standards or lugs 12 and 13, which serve to support a plate-likeerasing-shelf 14, the ends of which terminate in short rod-like portions15. The

rod-like portions are preferably constructed of separate pieces ofmetal, which after being properly formed are suitably attached, as

by soldering, to the erasing shelf or plate 14. The outer ends of therod-like portions are formed with holes which are tapped to receive theheaded screws 16, the latter passing through perforations in the lugs 12and 13 and being screwed tightly into the ends of the rod-like portions15. The erasing-plate is thus fixedly secured in position, atongueand-groove connection with the lugs 12 and 13 preventing rotationor lateral displacement. Mounted upon the erasing-plate are. themarginal paper-fingers 17 each of which is composed of a supportingportion 18 and a holding and guiding portion 19. The supporting portion18 preferably comprises, first, a guide block 20, which has milled orotherwise suitably formed longitudinally of its upper face a dovetailedgroove or mortise 21; second, a forwardly-projecting arm 22,whichterminates in bearing-eyes 23, and, third, a thumb-piece 24. As hereinshown, the bearing-block is constructed of a solid block of metal, andthe forwardly-projecting arm 22 is made of a thin metal strip, which ispunched or cut and af-' terward so bent or shaped as to form thebearing-eyes 23 and the thumb-piece 24. The arm 22, having thebearing-eyes and thumbpiece integral therewith, is suitably attached, asby soldering, to the bearing -block 20. Mounted in the bearing-eyes 23is ashort rod 25, the inner end 26 of which projectssufiiciently beyondthe adjacent bearing-eye to permit the said rod to be pinned to orotherwise suitably connected with the short offset arm 27 of the guidingand holding portion 19 of the paper-finger. A coiled spring 28 surroundsthat portion of the rod 25 which is between the bearing-eyes 23 andpresses the guiding and holding portion toward the platen, the rod 25serving as a pivot when the paper-finger is mounted in position on themachine. This latter operation is preferably accomplished by forming theunder side of the erasing shelf or plate 14 about midway its width withalongitudinal dovetail or tongue, which is shaped to conform to thedovetailed groove 2l of the bearing-block, the latter being mounted toslide longitudinally of the erasing-plate upon the said dovetail 29. Asbest appears in Fig. 2, the erasing-plate is fixedly supported inproximity to the top of the platen and slightly to the rear of its axis,

the blade or plate-like portion extending downwardly and forwardly inthe general direction of the delivery ends of the holding and guidingportions 19 of the paper-fingers. The latter are slidably attached tothe under side of the erasing-plate and project forwardly beneath thelatter and between it and the up per surface of the platen. This affordsa construction of neat and simple appearance, the connection between theerasing plate and the paper-finger being concealed from view and onlythe forward part of the latter being visible from the operatorsposition. Furthermore, by this construction the entire top surface ofthe erasing-plate is at all times left free and unobstructed. The offsetarm 27 of the guiding or feeding portion 19 enables the latter to beoffset inwardly or toward the center of the machine from the support orslide 18. By this construction the guiding or feeding portions of thepaper-feeding devices may be arranged far enough apart to engage thepaper near its side edges, while by reason of the offsets 27 the slides18 will at the same time be separated far enough to enable the fullwidth of the paper to pass between them. The top or leading edge of thepaper will, therefore, after passing upward out of engagement with theguiding or feed ing means pass over the erasing-plate, the top surfacewhereof, as previously stated, is always free and clear for makingerasures.

The invention is illustrated as applied to the Monarch type-writingmachine. It is to be understood, however, that the said invention is notlimited to the particular construction hitherto described, but that itmay be adapted to other forms of writing-machines and that variouschanges of construction and arrangements of parts may be effected withinits scope. The erasing-plate, for example, may itself be spring-mountedin the platenframe, while the coiled spring 28, which serves to pressthe guiding and holding portion of the paper-finger toward the platen,may be dispensed with and the said guiding and holding portion may berigidly connected with its supporting-arm. Such a modification isillustrated in Figs. 4 to 6, inclusive.

-In the modified construction the erasingplate 14 is provided with endportions 30, which are perforated longitudinally to permit of thepassage of headed screws 31, which are screwed into the lugs 12 and 13and which pass loosely through the end portions 30. The said screws 31act as pintles for the erasing-plate, the forward edge of which ispressed toward the surface of the platen by a spring 32, which is coiledabout the right-hand pintle 31 and one end of which bears against theerasing-plate, while the other end 18 held in or upon the lug 13. Theunder side of the erasing-plate is provided with a dovetail or tongue33, which extends longitudinally of the erasing-plate and upon which thepaperfingers 34 are mounted. Each of the paperfingers comprises asupporting-arm 35 and a guiding and holding part 36, which is rigidlysecured to the supporting-arm. The supporting arm or portion is formedwith a dovetailed groove 37, by means of which the paper-finger ismounted upon the dovetail or tongue 33, and thus secured to theerasingplate.

It will be noted that the general arrange ment of the parts is similarto that of the first-described construction and that the paper-fingermay be moved from side to side of the machine beneath the erasing-plateand between it and the platen by means of a thumbpiece 38, formed on thepaper-finger forward of the erasing-plate. The paper-finger spring 28 ofthe first-described construction is, however, dispensed with in themodified form, the paper-finger in the latter case having transmitted toit the pressure of the springmounted erasing-plate.

Other changes of form, construction, and arrangements of parts may bemade without departing from the gist of my invention.

What I claim as new, and desire to secure by Letters Patent, is
